This beginner-friendly, peaceful algae grazer spends its day hopping from rock to rock, mowing nuisance film and hair algae off live rock and glass. With big expressive eyes, a mottled camouflage pattern, and curious perching habits, it has loads of personality while earning its keep as a natural part of your cleanup crew.\u003c\/p\u003e\n\u003cp\u003ePair it with the rest of our \u003ca href=\"https:\/\/squeakysaquatics.com\/collections\/salt-water\"\u003esaltwater livestock\u003c\/a\u003e and \u003ca href=\"https:\/\/squeakysaquatics.com\/collections\/fish\"\u003emarine fish\u003c\/a\u003e to round out a reef or FOWLR system.\u003c\/p\u003e\n\u003ch3 style=\"margin:14px 0 4px;font-size:1.05em;font-weight:600;line-height:1.25;border-left:4px solid #006064;padding-left:8px;\"\u003eCare Guide\u003c\/h3\u003e\n\u003cp\u003eThe Lawnmower Blenny is hardy and easy to keep, which makes it a great first algae-eater for a maturing aquarium.
